Introduction

The DaySequerra M3 HD Radio

Multi-Tuner is the first broadcast quality monitor available with three

AM/FM tuners each complete with multicast capability. The M3 has been designed as the benchmark

in sensitivity (< 15.0dBf in FM) and reliability, and at the same time delivers the highest quality,

accurate monitoring of existing analog and HD Radio

AM and FM broadcast signals (THD+N <.005%

with stereo separation >90dB for HD Radio

FM signals).

Each of the three independent tuners in the DaySequerra M3 features an ultra low noise RF front-end

with built-in preselector and double-balanced mixer, low-jitter DAC and Class-A biased audio outputs

provide the highest fidelity reception and demodulation of HD Radio

programs, including display of

program applicable data (PAD) for MPS and multicast signals, including Apple “Buy Button” UFID.

Its robust, modular architecture ensures that the M3 will never become obsolete. The rugged M3

chassis houses dedicated hardware RF, audio and power supply modules that, along with firmware

updates via flash programmable memory, completely anticipates the growth of new HD Radio

services and programming. This design approach along with our product update program ensures that

a broadcaster’s investment in a DaySequerra product will continue to pay off well into the future.

Please read this manual thoroughly before operating your M3.
